OPEN-LINK-FUSE CARRIER.

Patented Oct. 1., 1912.

To all whom it 'may concern:

Be it known that I, lROBERT C. COLE, a citizen of vthe United States, residing at Hartford, in the county oit Hart-ford and State of Connecticut, have invented a new and useful Improvement in Open-Link-Fuse Carriers, of-whi'ch the'following is a speci ication.

It `is frequently desired to connectl the spring clips which are commonly provided for receiving inclosed electric fuses of the cartridge type, with an open link fuse. This invention relates to a device, adapted to carry an open link fuse, that can be in sert-ed into the spring clips provided for an inclosed fuse. i

The object of the present invention is to produce a very simple and cheap device which can be easily and quickly provided wth'an open link fuse and can be readily snapped into spring clips arranged for the commonly employed cartridge fuse. This object is attained by making an linsulating body of approximately the shape of a cartridge fuse, with conducting terminals that are adapted to engage the spring clipsin the usual way, and arranging means whereby these terminals can be quickly connected by the commonfuse link, the insulating body having a barrier between the terminals for separating them andfor increasing the length Vof the fuse path,and also having means `whereby the`device' can be easily. ma

nipulated and the fingers protected from contact with conducting parts.

Figure 1 of the accompanying drawings shows aplan of an open link fuse carrier of.

` this character which embodies the invention.

Vof other insulating material. Inte al with the body and extending outward y therefrom are wings Q. which form means for conveniently handling the body in such a way that the fingers are not likely to come in contact with any conducting part when the device is applied to or withdrawn from a live circuit. Integral with the body and wings and extending between the latter is a. transverse barrier 3. This barrier strengthens the wings and also lengthens the insulating path between the ends of the A body. v

l 0n each end of the insulating cylindrical body is a metal cap 4. A screw bolt 5 extends through each cap and the body, and onjeach screw bolt is a clamp nut 6. The upper surfaces of the body between the edges of the` wings and the ends are desirably flattened, and the ferrules are correspondingly shaped. This provides flat surfaces for the forked ends 7 of the fuse link, which are clamped to the conducting ,terminal caps by the nuts on the screws. The fusible member 8 ofthe link which extends from one `fork to the other, passes over the barrier between the wings.

A common open fuse link can be readily clamped to the terminals and then the device can be snapped into the usual spring clips employed for holding cartridgel fuses. These devices are particularly adapted to be used in connection with such a fuse block asis setforth in Patent No. 1,032,188, granted July `9, 1912, in place ofthe inclosed cartridgefuses shown 4and described therein. The invention claimedl is:

1. An open link fuse carrier having a cylindrical .body of insulating material with integral 'projecting wings and integral barrier between the \vings, conducting terminals encircling the ends of the bodies, and means for-clamping the ends cfa fuse link to said terminals.
